LOL OMG a units question:
7. One pascal is equivalent to
A 1 Nm
B 1 Nm2
C 1 Nm3
D 1 Nm–2
E 1 Nm–3.
don't like them XD

These questions require you to WORK IT OUT. From What? From the formula. Look at the formula booklet, find P=F/A. P is in Pascals, F is in Newtons, A is in m^2 so 1 Pa = Nm^-2.
Our prelim had a similar question, a Farad is what? Find the formula C=Q/V, Coulomb per Volt.
Get it? Don't try to remember (the teachers don't) - work it out!
:-)
Ooh thanks! The prelim was today and this question came up - I knew what it was, =O
*major shock*
I'll bear this in mind! :)
